Item type:Publication, Grounded Parallel RL, RC, and LC Immittance Simulators Using VDBAs and Passive Elements(2022-01-01); ; This communication suggests a grounded parallel RL, RC, and LC immittance simulator. In this circuit, two voltage differencing buffered amplifiers (VDBAs) with two passive components are proposed. The VDBA device's transconductance gain can be used to electronically adjust the realized equivalent resistance (Req), inductance (Leq), and capacitance (Ceq), which is conditional on the choice of the passive element. The effect of the VDBA's non-idealities on the realized simulator is studied in this research. The second order voltage mode bandpass filter is realized using the proposed active LC parallel simulator, which is simulated using the PSPICE simulation program to ensure that it operates as desired. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Voltage differencing buffered amplifier-based electronically tunable grounded capacitance multiplier(2019-03-16); ; A minimal realization of electronically adjustable capacitance multiplication topology with voltage differencing buffered amplifier (VDBA) is proposed. The proposed capacitance multiplier circuit is designed by means of two VDBAs and one floating capacitor. A capacitance multiplication factor is adjusted electronically through the ratio of two transconductances. The effect of the non-ideal gains of the VDBA is also taken into account and carried out. As an analog application example, the proposed capacitance multiplier circuit is utilized in the design of an electronically tunable first-order low-pass filter. PSPICE simulations with TSMC 0.25-µm CMOS technology are included to support the theoretical analysis. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, Electronically tunable resistorless capacitance multiplier employing VDBAs(2017-11-24); This work focuses on a circuit configuration for the simulation of the resistorless tunable grounded capacitance multiplier using the recently introduced active building block called voltage differencing buffered amplifier (VDBA). The proposed capacitance multiplier circuit consists of only two VDBAs, and one floating capacitor, without requiring critical matching conditions. The realized equivalent capacitance value can be tuned electronically through the ratio of the transconductance gain of the VDBA. The effect of the VDBA non-idealities on the realized equivalent capacitance has also been investigated in detail. As an application, an illustrative RLC low-pass filter using the proposed tunable capacitance simulator has been provided. In order to demonstrate the behavior of the circuit and confirm the theory, PSPICE simulation results with TSMC 0.25-µm CMOS technology are included. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, VDBA-based electronically tunable capacitance multiplier with a grounded capacitor(2018-07-02); ; This work presents an electronically tunable grounded capacitance multiplier circuit based on the voltage differencing buffered amplifier (VDBA), a recently introduced active building block. The proposed capacitor circuit requires only two VDBAs, one floating resistor, and one grounded capacitor. The circuit can be tuned electronically via the VDBA transconductance ratio. The effect of the VDBA non-idealities on the simulated capacitance value has also been discussed in detail. The usability of the proposed tunable capacitance simulator has been verified by realizing the fourth-order low-pass filter application with a Butterworth approximation. In order to verify the theory, the behavior of the circuits is evaluated with PSPICE simulation program using TSMC 0.25-µm CMOS process parameters. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, On The Realization of Simulated Lossy Inductors Using Voltage Differencing Buffered AmplifiersThis paper reports four topologies, all simulating floating/grounded lossy inductors, using voltage differencing buffered amplifiers (VDBAs) as active elements. The simulated equivalent resistance and inductance values of the simulators can be adjusted electronically through the VDBA transconductance parameter. Non-ideal gain outcomes of the VDBA on the realized inductor circuits are finalized. The critical active and passive sensitivities are obtained to be low. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, VDBA-Based series RC impedance simulator using single grounded capacitor(2018-08-13); ; This work presents an electronically tunable series RC impedance simulator circuit by means of the recently introduced active element, called voltage differencing buffered amplifier (VDBA). The proposed circuit employs only two VDBAs and one grounded capacitor, which is canonic in the number of components. The simulated equivalent element values can be tuned electronically through the VDBA transconductance gain. The circuit also does not require any component-matching conditions. The non-ideal gain effects of the VDBA on the simulated capacitance value are also evaluated and discussed. PSPICE simulations, which are in a close agreement with the analytical calculations, are included.
